1. Probabilities given:
Candidates doing home work P(H) = 0.4
Candidates not doing homework P(NH) = 1.0 - 0.4 = 0.6

Candidates passed from group of doing home work P(P/H) = 0.8
Candidates not passed from group of not doing homework P(NP/NH) = 0.9

Calculations:
Probability of candidates passed who did assignment P(P AND H) = P(H) * P(P/H) = 0.4*0.8 = ...
